Following this change of sponsorship, Cross Vetpharm Group Ltd. is no longer the sponsor of an approved application. Accordingly, it will be removed from the list of sponsors of approved applications in § 510.600(c) (21 CFR 510.600(c)). As a new sponsor of approved applications, Bimeda Animal Health Ltd. will be added to § 510.600(c) and the regulations amended to reflect this action. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these changes of sponsorship.

III. Withdrawals of Approval

Elanco US Inc., 2500 Innovation Way, Greenfield, IN 46140, has requested that FDA withdraw approval of NADA 140-939 for use of RUMENSIN (monensin) and TYLAN (tylosin phosphate) Type A medicated articles in the manufacture of combination drug Type C medicated cattle feeds because the product is no longer manufactured or marketed.

Also, Sergeant's Pet Care Products, Inc., 10077 S 134th St., Omaha, NE 68138 has requested that FDA withdraw approval of ANADA 200-600 for WORMX (pyrantel pamoate) Flavored Tablets because the product is no longer manufactured or marketed.

Elsewhere in this issue of the Federal Register, FDA gave notice that approval of NADA 140-939 and ANADA 200-600, and all supplements and amendments thereto, is withdrawn, effective March 25, 2019. As provided in the regulatory text of this document, the animal drug regulations are amended to reflect these actions.

IV. Technical Amendments

In addition, we are reformatting the regulations to present the approved conditions of use of halofuginone, monensin, and salinomycin in tabular format in the respective named sections of 21 CFR part 558. This action is being taken to improve the readability of the regulations.

V. Legal Authority

This final rule is issued under section 512(i) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C.360b(i)), which requires Federal Register publication of “notice[s] . . . effective as a regulation,” of the conditions of use of approved new animal drugs. This rule sets forth technical amendments to the regulations to codify recent actions on approved new animal drug applications and corrections to improve the accuracy of the regulations, and as such does not impose any burden on regulated entities.

Although denominated a rule pursuant to the FD&C Act, this document does not meet the definition of “rule” in 5 U.S.C. 804(3) because it is a “rule of particular applicability” under 5 U.S.C. 804(3)(A). Therefore, it is not subject to the congressional review requirements in 5 U.S.C. 801-808. Likewise, this is not a rule subject to Executive Order 12866, which defines a rule as “an agency statement of general applicability and future effect, which the agency intends to have the force and effect of law, that is designed to implement, interpret, or prescribe law or policy or to describe the procedure or practice requirements of an agency.”
